Run the command set l3-interface vlan-interface ipv6-nd mtu to include the MTU option is RA packets. This option assists the hosts in proper interface configuration. The advertised MTU is not verified to be consistent with the actual router interface MTU.
Run the command delete l3-interface vlan-interface vlan4001 ipv6-nd mtu to delete this option. This value is not configured in RA packets by default.
set l3-interface vlan-interface <vlan-interface> ipv6-nd mtu <value>
delete l3-interface vlan-interface <vlan-interface> ipv6-nd mtu
|vlan-interface <vlan-interface>||Specifies the VLAN interface name. The value is a string.|
|mtu <value>||Specifies the MTU value to advertise in RA packets. The value is an integer that ranges from 1 65535.|
- This example configures the advertised MTU value to 1000.
